I'm running VL7 and I have noticed my PC cannot get an IP address when trying to connect to my wi-fi router (using WPA2 security).Looks like dhcpcd refuses to start.Is there anything I can check (logs, dhcpcd configuration) ?

I've had a similar problem for a while, and used a fixed IP address instead. It ain't the prettiest solution, but it might be the easiest one (if it works). If you have a home router, it's probably safe to take an address somewhere in the 192.168.0.x range, where x is between 2-255.

You should be able to change this using wicd, which is probably in either the 'settings' or the network/internet submenu.

First a kernel module is loaded (driver) then wireless starts with authentication and then a request for an address occurs.

Open a command prompt window.

Now use su then enter root password there and press enter.

Type ifconfig -a and press enter.

I would expect there to be three entrieseth?l0wlan,ra or something like that.

If there are not three entries post the output from the above command herewith the wireless card name, make, model and revision number here.

If there are three entrees from the above command continue below.

Type this command iwconfig

Look at the output and see if there (usually first line) something to the effect of access point associated. If there is no association with an access point then that failed and it needs to be corrected.

If it is associated then follow below

Type this command and press enter:

ps -aux | grep dhcp

You should see results similar to this:/sbin/dhcpcd -t 10 eth0

If you do not see that then dhcp failed or did not start. Post the output from the above command here if it fails.

NOTE: You now need to know what your wireless card name is example wlan0. ifconfig -a may get you that information

Type:dhcpcd "card name her" (replace with your wireless card name here wlan0 for example) and no quotes

You probably will not see output from that command. Repeat the command above this to test for dhcpagain.

Those are the three areas that you can get started with and usually the problem. Your wireless card may not work in WPA2 in Linux even tough it works in windows.
